Battery cell assembly and method for assembling the battery cell assembly

Summary by NHIP

Battery Cell Heat Exchanger

The assembly places a plastic-framed heat exchanger between two battery cells to transfer heat via an internal liquid. A rectangular ring-shaped frame features a third side with a thermally conductive layer adjacent to the first cell's second side, while a fourth side holds the opposing layer.

Abstract

A battery cell assembly and a method for assembling the battery cell assembly are provided. The battery cell assembly includes first and second battery cells with a heat exchanger disposed between the first and second battery cells. The heat exchanger has a plastic frame and first and second thermally conductive layers. The plastic frame has an interior space extending therethrough. The first and second thermally conductive layers are disposed on opposite sides of the plastic frame to enclose the interior space, such that when a liquid is disposed in the interior space, heat energy is transferred from the first battery cell through the first thermally conductive layer to the liquid.
